A method for managing signal interference in a wireless communication device with a receiver involves detecting internal signal interference. Based on a predefined policy, the device determines the type of interference information to send to the network and transmits this information to the network interface, aiming to mitigate the interference. The network then performs corrective actions to reduce interference, such as handing over the device to another base station, adjusting the frequency range (low to high or to a new range), aligning signal resource blocks, instructing the device to lower its power, or switching to a modulation scheme with lower signal-to-noise requirements.

The method described for managing signal interference in a wireless communication device (as described in claim 1) is extended to a device utilizing carrier aggregation with two receivers. The first receiver processes first signals, while the second receiver processes second signals, both potentially subject to the described interference management process which includes detecting internal signal interference, sending data to the network, and the network undertaking corrective action such as handing over the device to another base station, adjusting the frequency range (low to high or to a new range), aligning signal resource blocks, instructing the device to lower its power, or switching to a modulation scheme with lower signal-to-noise requirements.
